BOWL HOLDING POT COVER FDR CENTRIFUGAL LIQUID SEPARATORS Filed Nov. 16', 1940 I Snnentor Clifford E. Butler;

Patented Jan. 13, 1942 EJNEE SE3 FAHEN newt. HOLDING Po'r COVER FOR oan'rarrnear. LIQUID SEPARATORS 1 Claim.

My invention pertains to improvements in closures, and particularly to bowl pot closures for centrifugal liquid separators, and the principal object of my improvements is to supply a device to be interposed between the bowl and bowl pot, to particularly close the latter when the separator is not functioning, removably.

The purpose of this invention therefore is to close the bowl pot when the separator is not functioning, to thereby prevent the entry of dust, insects or other intrusive elements thereinto, and permitting the removal of the closure before the separator is to be used.

I have achieved the above object by the means which is illustrated in the accompanying drawing, it being understood that various minor improvements and changes may be effected in the closure without departing from the scope of the invention or the protection of the appended claim.

Fig. 1 depicts the assemblage of my improved type of closure as above stated, including the closure shown fitted between the bowl pot below and the separator bowl above, and with the bowl pot and its closure displayed in medial vertical section, while the lower end part of the separator bowl is shown broken away. Fig. 2 is a top plan of the closure, and Fig. 3 a bottom plan thereof.

Referring to said Fig. l, the numeral III denotes the bowl pot of a centrifugal liquid separator, in which the bottom part is centrally apertured at M and with a surrounding spaced cylindric wall l3. The numeral l5 denotes the upper end of the separable bowl shaft as extending axially upwardly through the bowl pot II].

My bowl pot closure I is an integral single body, discoidal, with an outwardly projecting finger lug 8, perforated at 9 so that when not in use it may be suspended from a nail or other hanger. The closure has an upwardly projecting marginal ring or wall part 2. The numeral 3 denotes an upwardly directed central truncated cone 3, and has an upwardly directed concentric low wall part 5 whose interspace is crossed diametrically by a wall part 6. The wall part or ledge 2 is spaced from the base of the conical frustum 3, thus aifording therebetween a circular depression suitable to receive moisture or other droppings from the bowl It or other agencies. The conical part 3, upraised, may support the inwardly coned bottom part of the separator bowl l6, separably. The outwardly directed basal ring part of the bowl part I6 may removably fit within the cavity of the closure concentric wall 2.

As shown in Figs. 1 and 3, a plurality of equally spaced lugs I depend from the bottom part of the closure circularly, and as also shown in Fig. l, fit the inwardly directed part II of the bowl pot l0, removably. v

The upwardly directed diametral rib 6 seats in a slot across the lower end of a member |6a depending from the bowl I6.

The finger lug 8 may also be used as a stop when it strikes against another part of the separator structure to keep the bowl holder from turning around while the bowl is being unscrewed and taken apart. The connection at l6a locks the bowl Hi to the cross-bar 6, preventing relative rotation of the bowl thereon.

I claim:

A device of the character described, consisting of a circular member having an upright marginal rim, a central upwardly directed hollow frusto-conical part spaced from said upright rim, a coaxial upwardly directed hollow wall of less diameter than the upper end part of the frustoconical part and diametrically crossed by an upwardly disposed wall, a plurality of circularly spaced depending lugs coaxially disposed on the base of the circular member spaced from said upright marginal rim thereof, and a vertically ape'rtured radial horizontal lug projecting laterally from said marginal rim.
